Description

  The present invention relates to an automatic opening and closing device for automatically opening and closing a slide fastener used for a structure such as a tent or an industrial material such as a fish net.

  Slide fasteners are used in various products including clothes, and various types have been developed as components for opening and closing, which are excellent in strength, airtightness, and operability. Even in a structure such as a tent, it is possible to easily assemble by using a slide fastener when connecting divided parts. In industrial materials such as fish nets, a large-area fish net can be easily formed by connecting multiple fish nets with slide fasteners, and even when removed, they can be easily divided by opening the slide fasteners. Can be removed.

  However, when a structure such as a tent is increased in size, it is difficult to manually open and close the slide fastener. Further, even in industrial materials such as fish nets, in order to manually open and close the slide fastener, work in the sea is required, and there is a problem that opening and closing work is difficult. Therefore, an apparatus for automatically opening and closing the slide fastener without using human hands has been proposed.

For example, in Patent Document 1, a traveling gear is provided that meshes with a fastener claw through a window formed in a front piece of a Y-shaped cylindrical main body, and a guide gear is provided so as to mesh with a side surface of the fastener claw. Describes a device that opens and closes a fastener by rotating and driving a Y-shaped cylindrical body by a motor. Further, in Patent Document 2, an automatic opening / closing slider attached to a fastener guide cylinder and traveling along an engagement edge of the fastener is provided, and the automatic opening / closing slider includes a pair of left and right gears that are rotationally driven by a small motor. Are engaged with each other between the pair of left and right claw rows of the fastener, and when the pair of gears rotate, the guide cylinder and the automatic opening / closing slider move along the engagement edge of the fastener to move the fastener. The point which was made to open and close is described.

A portion of the holding body 20 corresponding to the slider 1 is cut out along the outer shape of the left and right upper wing pieces 2, and the cut portion is fitted along the upper wing piece 2. Since the upper wing piece 2 has a shape that bulges outward in accordance with the bifurcated shape of the sliding path 4, the fitted holding body 20 can move only in the vertical direction without shifting in the front-rear and left-right directions. It is attached. Then, the holding body 20 and the left and right upper wing pieces 2 are connected by an elastic plate piece 21, and the base body 10 and the holding body 20 are connected by a spring member 22, so that the entire holding body 20 is lowered. It has come to be energized. Although not shown in FIG. 1, since the service tooth row of the slide fastener is sandwiched between the base 10 and the holding body 20, the holding body 20 is urged downward to be always on the upper surface of the service tooth row. The contact state is set.

  A plurality of guide members 11 and 23 are provided at opposing positions on the upper surface of the base 10 and the lower surface of the holding body 20, respectively. The guide members 11 and 23 are formed in a disk shape having a predetermined thickness, and shaft portions provided at the center portions thereof are respectively inserted into shaft holes formed in the base body 10 and the holding body 20. It is attached so that it can rotate freely. The guide members 11 and 23 are appropriately arranged on both sides of the path along which the service tooth row moves so as to guide the service tooth row in an open state, and the guide members 11 and 23 move while being in contact with the guide member. In addition, since the guide member rotates, a smooth movement operation with little friction can be performed.

  A pair of gears 30 and 31 that mesh with each other are provided as a gear mechanism between the base 10 and the holding body 20. The gears 30 and 31 have the same diameter and the same number of teeth. The gear 30 is attached to a shaft body 30a protruding in the center so as to be rotatably supported in a shaft hole formed in the base body 10. Further, the gear 31 is rotatably supported by a shaft hole having a shaft body 31a projecting from the center and penetrating the base body 10, and a lower portion of the shaft body 31a projects downward through the base body 10. .

The reduction gear 42 is fixedly attached to the lower portion of the shaft 31a of the gear 31, and is rotated by being transmitted to the gear 31 via the drive gear 41 and the reduction gear 42 by the rotational drive of the motor 40. The gear 30 is also rotated in synchronization with the rotation of the gear 31.

  FIG. 3 is a top view relating to the automatic opening / closing device showing a state in which the pair of tooth dentitions 7a and 8a of the fried fastener is mounted. The holding body 20 is omitted for easy understanding. The pair of service tooth rows 7a and 7b are respectively led out from the sliding path divided into two forks of the slider 1 and are in an open state in which the engagement is released. Each of the dentitions is guided on both sides by the guide member 11 and spaced apart from each other along a bifurcated sliding path so that both sides of the gears 30 and 31 constituting the gear mechanism are arranged. Be guided to. Then, the engagement tooth head of one engagement tooth row 7 a is engaged with the gear 30, and the engagement tooth head of the other engagement tooth row 7 b is engaged with the gear 31. A guide member 11 is provided on the opposite side of the gear teeth gear head that meshes with the gears 30 and 31, and guides the gear teeth row so that the gear and the gear tooth head are not disengaged. The dentitions engaged with the gears are guided on both sides by the guide members 11 so that the distance between them is substantially the same.

  As described above, the engagement teeth rows 7a and 7b of the slide fastener are set so as to be engaged with the gears 30 and 31, so that when the gears 30 and 31 rotate in synchronization, the engagement teeth row 7a and 7b The gears 30 and 31 move in the front-rear direction along the dentition row while meshing with the dentition head. When the gears 30 and 31 move, the base body 10 to which the gears are attached also moves, and the slider 1 moves along with the movement of the gear together with the base body 10.

  Since the dentitions 7a and 7b are sandwiched between the upper surface of the base 10 attached along the sliding path 4 of the slider 1 and the holding body 20 biased downward, the sliding of the slider 1 It is regulated along the road 4.

As shown in FIG. 5 (a), the tooth rows 7a and 7b are led out into the sliding path 4 of the slider 1, and the base body 10 and the holding body 20 are disposed along the sliding path 4. Since the holding body 20 is urged downward, the distance between the two is set to be substantially the same as the vertical width of the engagement teeth row 7a and 7b. In addition, the slider 6 of the rail fastener has a recessed portion 8a and a protruding portion 8b led out into the sliding path 9 thereof.

  As shown in FIG. 5B, the dentitions 7 a and 7 b pass between a guide member 11 projecting from the upper surface of the base 10 and a guide member 23 projecting from the lower surface of the holding body 20. Therefore, the gear teeth 30 and 31 are securely meshed with the gear teeth heads of the gear teeth 7a and 7b, and the gears 30 and 31 are rotated synchronously by the rotation drive of the motor 40. The gears 30 and 31 move while meshing with 7a and 7b. The groove 8a and the protrusion 8b of the rail fastener are integrally formed at the side end of the sheet material made of synthetic resin. Even when the fitting between both is released, the sheet material itself has a predetermined height depending on the strength of the sheet material. Is retained. And if the service tooth row 7a and 7b are guided by the guide member and the space | interval between both expands gradually, the space | interval between the concave strip part 8a and the convex strip part 8b will also expand in connection with it ( (Refer FIG.5 (c)).
